absolutely necessary to pasteurize horse poo?
    #7217185 - 07/24/07 08:52 AM (16 years, 6 months ago)

i've spawned a few jars to pasteurized horse poo already. but as i was about to spawn today i found some white patches of growth in my last pasteurized bag. it looks like some sort of mold and i'm sure it can't be good for the health of the fungus i'm trying to grow, so...

i'm a little bit pressed for time and was wondering if it's possible to spawn to unpasteurized poo. it's good and old and doesn't seem to have too many bugs in it.

anyone have any advice?
or should i hold off and bake another bag?

1) I don't understand...white patches? Sounds like mycelium to me, unless it has the look of pre-spore trich.

2) I definitely don't understand. Why would deliberately *not* bringing your substrate to over 130, the point of thermal death for molds, help?

You certainly could not pasteurize...but we do it for a reason. Unpasteurized substrate will very likely yield to molds. It sounds like you may well not even have a problem.

I would also add that the shelf life of something pasteurized is pretty much only a couple hours if not a day. Let it sit much longer than that and not only will your moisture content go to shit (no pun intended) but you'll also get just as many new contaminates in it as possible.

Pasteurization is essential, the only other alternative is sterilization...but the reason we choose pasteurization over sterilization is because the thermophilic microbes that survive the process are beneficial for triggering fruiting and for keeping away some types of contaminates.

If I Recall Correctly, that is...

i'm sorry i was unclear. over the last couple of days i spawned some jars to some bags of pasteurized horse poo that looked perfect. but today i opened a new bag of already pasteurized horse poo and found small while moldy patches ( i think the bag was too wet and sat too long. i also might not have gotten the temp up high enough during pasteurization). that poo has had no previous contact with any mycelium.

so, no, the white patches are not mycelium. and i don't want to add any colonized jars to it.

so i'm wondering, since pasteurization takes so long, if i can spawn safely to unpasteurized horse poo.

in other words, how big is the risk?

Well you just got contamination on *pasteurized* shit. I wouldn't really give it a go without.

Too big to be worth wasting your time and spawn.

Pasteurizing/sterilizing the poo is absolutely necessary.

It really is. It's bad enough to get a contaminate in a jar and having to waste the grain and inoculate on just that amount...but to willingly take a risk on several pounds of substrate - which is probably the most expensive recurring cost in the process - is really unwise.

The odds of _not_ getting a contaminate in that instance become infintismal...all things considered.

... i pay for bulk subs... worth every penny. www.mycopath.com

i don't live in a place condusive to pasteurizing my own poo, aging it and leeching it in an apt complex, outside, on a tarp, wouldn't bode well with the apt. manager.

perhaps there is a small alleyway close to/behind the dumpsters/parking garage - people would just think it's rotten garbage...

I've been moving towards creating my own compost lately an i'm going to see how that fairs. I will say, it was the most amazing thing to find out that composted oak leaves (rather acidic) and coffee grounds (mild buffer) can yeild a net pH of a perfectly neutral 7.0.
